Underlined: most discriminant words shared between codons and 3-mers in whole genomes, for a considered niche category. Bold characters: most discriminant words shared between cells and mobile elements, for a considered niche category. In parenthesis: statistically non-significant frequency differences based on a t-test (p ≥ 0.01), in a considered niche category
